Finding information about the different types of mice in Connecticut was not as easy as I thought. Some information was incorrect, others were not enough, and some sites were just irrelevant.
That is why I created 7 Common Types of Mice in Connecticut.
While there are over 1000 species of mice in the world, this article will focus specifically on Connecticut or its surrounding areas, along with the role mice have in its ecological environment.
7 Types of Mice in Connecticut

You will know them by their extremely long tails, long hind feet, yellowish-orange color along their sides, and darker brown band on their back.
The name ‘jumping mouse’ comes from the fact that they can jump high. This species of mouse has the ability to jump for up to a distance of 3 feet.
Another thing you can use to identify these types of rats is the bicolored tail. Looking into it, you will find that it has a combination of two colors including the white underside and the dark brown upper.
When it comes to feeding, these rats eat various types of foods including fruits, grasses, and seeds. They also eat insects and some species of spiders. Therefore, they help control their populations, and that is the important ecological role they play.
In addition to the ecological role of controlling or reducing insect populations, these rats or mice also help in the dispersal of seeds. They are under a great threat of habitat loss, and fragmentation.
#6. Eastern Harvest Mouse (Microtus ochrogaster)
